Bench cable or bench cable with connecting sleeve

So-called bench cables are used to supply energy to large equipment such as excavators and conveyor belts in mining and bench lines operated with a transmission voltage of 10 to 30 kV and accordingly have individually shielded cores. In the course of such cables and cables are sometimes connected sleeves, the structure of which largely corresponds to the cable structure are adjusted so that they can be reeled up and down together with the cable or line.

In a known connecting sleeve for connecting two Line pieces of a bench line are the shield wires of the cores at the two ends of the connecting sleeve bundled, and these wire bundles are inserted into the interstices of the interconnected cores, the corresponding wire bundles of the two line ends are connected to one another via notch sleeves or compression sleeves. (DE-GM 74 42 643) 3ei this known sleeve construction there is a risk that under the influence of tensile stresses the bundled shield wires are pulled out of the compression sleeves or notch sleeves.

The innovation eliminates this risk. This is achieved constructively in that the screen wires each are inserted at both ends of the connecting sleeve in notched sleeves or compression sleeves and that for electrical connection a copper cable is provided from two notched sleeves or compression sleeves each assigned to a gusset space, which consists of three fine or ultra-fine stranded conductors braided into a braid.

The copper ropes used according to the innovation have a very large longitudinal expansion and thus ensure that they are also subject to high tensile stress on the line or cable in the area of the connecting sleeve not from the notch or Press sleeves can be pulled out. This is a disruptive factor in the operation of the line and expensive repair work switched off.

shown in the figure.

The figure shows a connecting sleeve with which the two Line pieces 1 and 2 are connected to one another by a bench line. The shield wires 3 of the cores 4, 5, 6 and are removed from the wires and combined at the ends of the connecting sleeve to form wire bundles 8 and in a notched sleeve or compression sleeve 9 or 10 fixed. The wire bundles and the compression sleeves are in the corresponding interstices inserted between wires 4 and 5 or 6 and 7. Corresponding wire bundles and compression sleeves are in the same way inserted into other interstices of the veins. Between the compression sleeves 9 and 10, the copper cable 11 is arranged on the ends of which the compression sleeves 9 and 10 are also pressed on. The copper rope 11 consists of three finely stranded Stranded conductors 12, 13 and 14, which are braided into a loose braid. Accordingly, the copper rope 11 is in Stretchable lengthways.
